Dry‐Season Water Deficits in the Southwestern Amazon Under High Emissions

International Journal of Climatology, EarlyView.
Projected climatic water deficit in the study region indicates a longer and more intense dry season, with delays in the onset of the wet season under higher emission scenarios. These changes, particularly, pronounced under SSP5‐8.5, suggest increased ecological vulnerability and greater seasonal water stress.

Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America [PDF]

, 1992
We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP) for potential vegetation in North America. Data on pool

How Well Do CMIP6 Models Simulate the Influence of the West African Westerly Jet on Sahel Precipitation?

International Journal of Climatology, EarlyView.
Climate models generally reproduce the WAWJ and August peak but simulate its onset prematurely and too strongly relative to ERA5. CMIP6 simulations struggle to reproduce the jet–precipitation relationship in the Sahel and underrepresent associated moisture transports.
